Well I guess we beg to differ. My theory is more reinforcement and less core provides stronger ride that still retains good flex characteristics. When you increase the core you increase stiffness but at the detrement of strength. The thinner board with more reinforcement will flex more before it fails and fail well after the stiffer thicker core fails due to its lower ability to flex.downunder wrote:Nomad boards are rare like a hens teeth at my local. Have no idea how they ride.
2mm carbon on tips is brittle as. One drop from only 30cm on a floor and will break. The full carbon board might be very light, so it doesn't break when dropped.
However, the 143x43cm with your layup will make a =>4kg board. That is not light. Using kevlar will make it darker over time since not UV stable (even with heaps of UV varnish). Using a wide carbon is very, very difficult since it will open some threads and expose the wood underneath. It also 'drinks' epoxy. The middle pic carbon is useless as well as right pic kevlar coz used only for curved 3d shapes in multiple layers (say 5-10). Good you posted this pic's tho, so we can comment. This is the real experience answer.
8mm tapered in centre does not edge well at all without the boots.
The bigger question for TomBoy is a springback tho.
Your 12mm paulownia board with just 120 of fg and 200 uni on top will be stiff but it wont be strong. It will fail when over flexed well before my thinner cored boards. Well before. But if it doesn't break then who cares if its not as strong!..downunder wrote:Yes, we do.
I know the stiffness numbers. And I know how strong my 12mm Paulownia board is with just 120g biax FG on bottom and 200g UNI on top (+ carbon tape). Less than 2kg board.
"The thinner board with more reinforcement will flex more before it fails and fail well after the stiffer thicker core fails due to its lower ability to flex." - this is only true for a foam boards. Using wood completely changes a picture. Using balsa and jarrah is not the same, I hope we agree on that.
But back to helping this guy, I think the inserts position on cedar wood is not great. Cedar we have here is a way more softer than P. wood. Consider reinforcing your inserts with at least 2 layers of FG, to protect the inserts pulling out (not so much pulling but making them loose and letting the moisture in).
